diffx-rdiffx-ldiffx {transx} | R Documentation |
Returns suitably lagged and iterated difference
diffx
computes simple differences.
rdffix
computes percentage differences.
ldiffx
computes logged differences.
diffx(x, n = 1L, order = 1L, rho = 1, fill = NA)
rdiffx(x, n = 1L, order = 1L, rho = NULL, fill = NA)
ldiffx(x, n = 1L, order = 1L, rho = 1, fill = NA)
x |
Univariate vector, numeric or ts object with only one dimension. |
n |
Value indicating which lag to use. |
order |
Value indicating the order of the difference. |
rho |
Value indicating the autocorrelation parameter. The purpose of this parameter is to provide quasi-differencing assuming the value falls within 0 and 1. |
fill |
Numeric value(s) or function used to fill observations. |
x <- c(2, 4, 8, 20)
